Electronic device for adjusting frequency of reference signal used to generate RF signal

An electronic device comprising:

• a plurality of antennas;
• a processor;
• a radio frequency integrated circuit (RFIC) configured to:
• generate a first radio frequency (RF) signal in a frequency band to be used in cellular communication by mixing a first baseband signal with a first reference signal,
• output the first RF signal to a first antenna among the plurality of antennas,
• receive, from a base station through the first antenna, a second RF signal in a frequency band to be used in the cellular communication,
• generate a second baseband signal by mixing the second RF signal with a second reference signal, and
• output, to the processor, the second baseband signal;
• and
• a wireless communication circuit configured to support wireless communication other than the cellular communication,
• wherein the processor is configured to:
• obtain information about a quality of a third RF signal received by the wireless communication circuit through a second antenna among the plurality of antennas,
• based on the quality being identified to be less than or equal to a reference value, obtain, from the second baseband signal received from the RFIC, a control signal for establishing a communication channel between the base station and the electronic device, and compare the control signal with frequency configuration information, the control signal comprising first information indicating a first frequency band and a first bandwidth of a transmission channel of the communication channel and second information indicating a second frequency band and a second bandwidth of a reception channel of the communication channel,
• based on the comparison of the control signal with the frequency configuration information, determine that information, in the control signal, matching a condition for causing desense of the third RF signal received by the wireless communication circuit through the second antenna exists in the frequency configuration information, and
• based on the quality being identified to be less than or equal to the reference value and based on the determination that the information matching the condition exists in the frequency configuration information, adjust a frequency of the first reference signal to an alternate frequency indicated by the frequency configuration information corresponding to the control signal.
